Comment high-value scam (Score 1) 79

We see these ideas that are obviously nonsense all the time. This one has been picked apart by multiple people with industry experience already.

What these things are is essentially the venture capital version of the scam mails you get in your mailbox every day. If you make it big enough and insane enough, someone with more money than brains will think he spotted an opportunity that everyone else missed and will invest.

Why is it, you think, that 99% of these things vanish without a trace after an initial storm of publicity?

It likely means demolishing a lot of existing houses and businesses to make room for the train

It doesn't. What it means is cutting through a lot of big parcels whose owners have big money, so they can be big impediments. There has to be a happier medium than this between respect for individual private property ownership and the needs of the many, but we are clearly uninterested in finding it in this country.

The whole point of the label "Dark Energy" is it's a filler for an unknown that still needs to be explained.

The whole point of dark energy is to explain why the cosmos is expanding more than it theoretically should be. If it isn't, then you don't need dark energy, or if it isn't expanding as much as formerly believed then you don't need as much of it.

Thus 5x3 becomes 5x5x5 or 3x3x3x3x3 instead of "STFU and memorize your times tables."

I'm fine with the repeated addition. My objection is the OR in your statement. Apparently not. The question was 5x3 and the kid wrote 5+5+5=15 and got marked wrong with no explanation because the teacher wanted 3+3+3+3+3=15. So I guess that you would have had a 50% chance of being marked wrong on a 2nd grade arithmatic worksheet as well, as absurd as that is. Correct answer notwithstanding.

BTW, that's not at all new. We covered multiplication that way in the 3rd grade back in 1975. Memorizing the table was just to make it quicker. I quickly "discovered" the commutative property while looking at the multiplication table and cut my memorization load in half. The part that confused the father was why is 5x3 = 5+5+5=15 "wrong".

As for 37+55, we decomposed that in the '70s as well, but I soon decided the easier decomposition was 37+55= 87+5 = 90+2=92. So I would say that meme was just someone wanting to complain. Of course the "old way" ends up in 30+50+10+2 anyway.

Shut up and memorize was not in practice during the education of the parents of today's students.
